Bzik,
Welcome to JOF
"Jayco 222SL tongue weight?" (thread title)
Since you mentioned you will be loaded close to the 222SL GVWR of 8,000lbs, an ideal loaded tongue would be 1,040lb to 1,200lb range (13% to 15% of the gross loaded weight). At 7,500lb gross = 975lb to 1,125lb range.

I would take your F-150 under loaded conditions (passengers, full fuel, etc.) to a CAT scale and weight, subtract the CAT weight from your F-150's GVWR..., the delta will be your actual remaining "
available" cargo capacity for your TH's loaded tongue weight and WDH weight. Don't forget to account for any truck-box cargo weight not in account at the CAT.
OR.......
Take your TV/TH under "fully loaded" conditions to a CAT Scale and perform a 3-pass weigh-in. The CAT information will confirm WDH rating/adjustment, tongue weight, axle weights, etc..
CAT Scale how-to:

If your maxing out your F-150 (GVWR and/or Rear GAWR, etc.) then you may not like it's performance/handling towing your loaded TH cross country through the mountains..., especially in less than ideal towing conditions.
